| 摘要 |
The following invention relates to an improved LCD Backlight, particularly to an improved arrangement of the optical scattering dots within the light guiding plate. The light guiding plate (22) comprises a lower surface which is formed with a plurality of optical scattering dots (23a-23d), which scatter and reflect the light beams to convert the light beams into a uniform surface light source, characterised wherein the surface area of each optical dot decreases as a function of its distance from at least one of the three edges comprising the LED lights (26). |
